Computational Fluid Dynamics(CFD)has been applied in many industrial fields,and can be used to validate the development and design of combustion fields for large burners through CFD technology.Use the finite element software Ansys to mesh the inner chamber of the burner,process the simulation experiment results,and verify the working pressure and temperature of the burner.Through CFD simulation experiments,it has been verified that the newly developed burner can ensure stable pressure and temperature.By applying CFD technology to the research and development of mechanical equipment,it can break through the limitations of traditional calculation methods,gain a more intuitive understanding of the internal environment of the equipment structure,accurately grasp internal information,and improve equipment performance.
